alleryAn ideal solution forms when A-B forces against A-A and B-B are:
AFully absent
BNearly equal
CMuch weaker
DMuch stronger
Answer & Solution
Correct answer: B. Nearly equal
1. In the pure liquids only A-A and B-B interactions exist.
2. Mixing brings in A-B interactions as well.
3. If all three are nearly equal, the solution is ideal.
